I claim: v

l. Heating apparatus comprising a refractory wall adjacent a heat-absorbing mass, a troughshaped, heat-radiating member so mounted on said wall as to define therewith a passage for conveying heating fluid, means for supplying heating fiuid to said passage, andv projections from said wall extending into said member providing baies around which said fluid must pass.

2. Apparatus for supplying heat to a heatabsorbing mass comprising a refractory wall adjacent said mass, slots formed in said wall,

-troghshaped metal, radiant members having their edges disposed in said slots to define with said wall a plurality of passages for heating fluid, and means for supplying heating uid to said passages,

3. Heating apparatus comprising a refractory wall adjacent a heat-absorbing mass, a heatradiatingmember of metal plate bent to trough shape and so mounted on said wall as to dene therewith a passage for conveying heating uid, and a burner penetrating said wall for supplying heating fluid to said passage.

4. Apparatus for supplying heat to a heatabsorbing mass comprising a refractory wall adjacent said mass, a plurality of radiant members of metal plate bent to trough shape and mounted on said wall adjacent said mass with their edges embedded in said wall to define therewith a plurality of passages for heating fluid, and burners for supplying heating fluid to said passages.
